No claim in the EU register
- The EU register of health claims has no claim for this ingredient. In the EU, the review of many plant-based claims (about 2,000) remains on hold, and those claims are not listed in the register.
In the EU, only health claims whose evidence has been assessed by the European Food Safety Authority (EFSA) and authorised by the European Commission may be used on food. “Not authorised” means the evidence for that claim was not established under EU standards — not that the ingredient is dangerous.
